Current treatment options in oncology

Head and neck cancers can be used as a paradigm for exploring "big data" applications in oncology. Computational strategies derived from big data science hold the promise of shedding new light on the molecular mechanisms driving head and neck cancer pathogenesis, identifying new prognostic and predictive factors, and discovering potential therapeutics against this highly complex disease. Big data strategies integrate robust data input, from radiomics, genomics, and clinical-epidemiological data to deeply describe head and neck cancer characteristics. Thus, big data may advance research generating new knowledge and improve head and neck cancer prognosis supporting clinical decision-making and development of treatment recommendations.

ReviewMetastatic Colorectal Cancer to the Peritoneum: Current Treatment Options.
Peritoneal metastases (PM) are common in advanced-stage colorectal cancer (CRC) patients representing the second most common metastatic site of CRC. In the past, this clinical situation was treated with palliative intent. ⋯ Notably, the surgical approach of CRS/HIPEC has been effective offering a prolonged survival with curative intent in patients with colorectal PM. This article reviews and highlights the recent evidence of CRS and HIPEC as well as current research going on in this form of locoregional treatment in the setting of peritoneal metastases of colorectal cancer.

ReviewImmune Checkpoint Inhibitors in Early-Stage and Locally Advanced Non-Small Cell Lung Cancer.
Surgical resection ± chemotherapy ± radiation or stereotactic body radiation therapy (SBRT) are established treatment modalities for resectable stage non-small cell lung cancer (NSCLC), and concurrent chemotherapy with radiation is the therapy of choice for unresectable locally advanced disease. Despite treatment with curative intent, most patients subsequently relapse and develop distant disease. ⋯ The preliminary data from ongoing trials suggest that the integration of checkpoint blockage into the treatment of early-stage and locally advanced NSCLC is safe, tolerable, and has the potential to improve outcomes without adding substantial toxicity. In the current review, we provide an overview of the emerging data on the role of PD-1/PD-L1 and cytotoxic T lymphocyte-associated protein 4 (CTLA-4) inhibitors in the treatment of early-stage and locally advanced NSCLC, with a focus on ongoing clinical trials and combination strategies.

Polycythemia vera (PV) is the most common myeloproliferative neoplasm (MPN), the ultimate phenotype of the JAK2 V1617F mutation, the MPN with the highest incidence of thromboembolic complications, which usually occur early in the course of the disease, and the only MPN in which erythrocytosis occurs. The classical presentation of PV is characterized by erythrocytosis, leukocytosis, and thrombocytosis, often with splenomegaly and occasionally with myelofibrosis, but it can also present as isolated erythrocytosis with or without splenomegaly, isolated thrombocytosis or isolated leukocytosis, or any combination of these. When PV is present, the peripheral blood hematocrit (or hemoglobin) determination will not accurately represent the actual volume of red cells in the body, because in PV, in contrast to other disorders causing erythrocytosis, when the red cell mass increases, the plasma volume usually increases. ⋯ Only a direct measurement of both the red cell mass and plasma volume can establish the correct diagnosis. In managing a PV patient, it is important to remember that PV is an indolent disorder in which life span is usually measured in decades, even when myelofibrosis is present, that chemotherapy is futile in eradicating the disease but does increase the incidence of acute leukemia and that hydroxyurea is not safe in this regard nor is it antithrombotic. Phlebotomy to a sex-specific normal hematocrit is the cornerstone of therapy and there now exist safe remedies for controlling leukocytosis, thrombocytosis, and extramedullary hematopoiesis and symptoms due to inflammatory cytokines when this is necessary.

Based on the available literature, mostly derived from retrospective or non-randomized phase I or II studies, it is difficult to define an optimized treatment approach for patients developing Richter's syndrome (RS). Early recognition of chronic lymphocytic leukemia (CLL) patients presenting clinical features suspected for a transformation is useful to avoid exposing them to multiple lines of therapy that, being targeted to CLL progression, have poor efficacy against RS. Because of the low specificity (~ 50-60%) of clinical signs of RS (such as rapid and discordant bulky localized lymphadenopathies, elevated LDH levels, emergent physical deterioration, and/or fever in the absence of infection), a 18FDG PET/CT and a biopsy are recommended to confirm RS. ⋯ If a clonal relationship is confirmed (the most common situation), rituximab-CHOP-like treatment does not guarantee long-lasting remissions, and should be used as induction therapy followed by consolidation with a stem cell transplant in physically fit patients. If the CLL and RS are clonally unrelated (the less common situation), the management should be that of a de novo DLBCL. In the setting of the rare Hodgkin lymphoma variant of RS, which is usually clonally unrelated to the CLL, ABVD with or without radiotherapy may be curative of the aggressive lymphoma.
